I have an Abit AV8 socket 939 motherboard which stopped booting up a couple of days ago. LEDs on the board light up, fans start spinning, and the POST indicator displays numbers, but nothing comes up on the screen. After about 5 seconds a two tone alarm starts going off. The tones are of equal length. I don't know much about POST, but according to the manual I think it's getting all the way through. The final code is "9.0." - "Complete uGuru initial process. AWARD BIOS take over booting job".
I've tried resetting the CMOS both with and without the battery. I've tried another PSU, different memory, memory in different slots, and removing every component (HDDs, optical drive, PCI soundcard, video card) - same result every time. Any suggestions as to what else I can try before trashing the motherboard?
